Are you sure you shaved properly? You have to use a clean blade and you want to make sure you let it soak in the warm water for a few minutes, then apply shaving cream and let it soak for another couple minutes, and then shave WITH the hairs. So down, not up. And only go over each area like once or twice. Don't keep shaving the same area or it irritates it. I love shaving! It's fast and easy. And the more you do it the more you get used to it and you don't get those bumps anymore.
